My name is Patrik Karlsson Karlström, and I am an open source programmer as well as an avid Linux user since 2006.

Here you’ll find a variety of projects that I develop. You can keep up with my work by reading my blog or over at github.

  1. Hi Patrik,

    I downloaded Mapollage a few days ago and think it is awesome. I am a surveyor and take pictures in the field to document things I see. The program will be a great way to share my pictures with others. Is there way for me to support your work?

    Thank you very much for sharing your projects.

    1. Hi Dwayne,
      I’m happy to hear that you like Mapollage.
      Regarding support; feedback, requests and bug reports are always welcome! 🙂

      I’m also working on a new project called Mapton, among other things, it has a simplified version of Mapollage integrated under the name of ‘Photos’.

      Check it out at https://mapton.org

    1. I would say that it depends on a couple of things, some of them being
      1. Your hardware specification
      2. The number of photos
      3. Your mapollage configuration (thumbnail creation)
      4. The number of files you are scanning an if they reside on your computer or not.

  2. i am running your tool mapollage-1.1.1 on Windows 7 x64 system. I have no program using the GUI, but i cannot make it work from command line. here is an example:
    C:\Downloads\mapollage-1.1.1>mapollage.exe -v

    nothing was displayed on the window.

    I am not sure what is going on here.


    1. Thanks for reporting that, I can confirm I got the same odd behavior on Windows.
      The output is displayed if using the cygwin terminal though.

      I will have a look at this.

  3. Hello, How may I customize the default pin symbol to something more relevant to my work? I’m not a programmer but if you can direct me to where the code exists and how to access it, I think I could make a change. Thank You!

  4. Thank you very much for the new version of jotasync 0.3!
    Where are my configured jobs of jotasync 2.9 (stored in ~/.config/jotasync)?

    Best regards,


    1. To make it clear: The file ‘jobs.json’ is still there, but I can’t see the jobs on the big buttons in jotasync.
